The Lobste.rs invitation tree, visualized
Lobste.rs makes its entire invitation tree public. I scraped it and built this interactive visualization. Some interesting patterns: - The top 10 inviters are responsible for ~40% of all users. - The tree is surprisingly shallow: Most users are only 4-6 generations from the founder. Max depth is around 15. Built with Sigma.js for WebGL rendering. Works on mobile too. (I am seeking a lobste.rs invite if anyone's willing! – my email is in my profile)

We spent a lot of time working on this, including the demo, and we'd love some feedback. It might take a little bit of time to load if lots of people are trying the demo, so please try to be patient. We spent a lot of time to ensure you'll be impressed. Feel free to email us at tony or chuck @graphmuse.com if you'd like to discuss further!

I've always dreamed about a project like that when looking at status boards at other companies. We finally had the time to do our own. Here are some photos: http://www.flickr.com/photos/robert_olejnik/sets/72157633736087905/ The stack: Django, mustache.js, Chart.js, Bootstrap and custom Supybot plugin. Maybe will be inspiration for someone else ;-) Do you guys have similar status boards? Cheers, Robert.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
